pain after masterbation!

So on Sunday i materbated with my dildo (only rubbing, it was not in me). and i kept going after orgasm and i ended up oragasming a total of five times it was awesome. the next day as  usual when i masterbate too much, i felt like i was cramping and such like i would be on my period. i figured it was from me doing it so much. and i had regular clear discharge and rarely some little blood. however  i was not, and i did not get on my period.but now down in my pelvis area it just feels sore and hurts. when im up and walking it hurts. it was like that for a day or two. then i woke up and felt better.however that night, which was last night was the worst. i felt like i was going to puke. i could not walk straight due to the pain. i tried sitting on the toilet and that was  VERY painful. it was hard to sleep with such pain and laying in my bed was the only way to not feel it as much. now im up today and i still feel the pain but its not as bad as last night. i fear tonight will be the same as last night. whats wrong with me?

the pain is on the left side of my pelvis area and down. im 17 and female.
